IDT82V3012 - T1/E1/OC3 WAN PLL

General Description

The IDT82V3012 is a T1/E1/OC3 WAN PLL with dual reference inputs.

It contains a Digital Phase-Locked Loop (DPLL), which generates low jitter ST-BUS and 19.44 MHz clock and framing signals that are phase locked to an 8 kHz, 1.544 MHz, 2.048 MHz or 19.44 MHz input reference.

Key Features

  • Supports AT&T TR62411 and Telcordia GR-1244-CORE Stratum 3, Stratum 4 Enhanced and Stratum 4 timing for DS1 interfaces.
  • Supports ITU-T G.813 Option 1 clocks.
  • Supports ITU-T G.812 Type IV clocks.
  • Supports ETSI ETS 300 011, TBR 4, TBR 12 and TBR 13 timing for E1 interface.
  • Selectable reference inputs: 8 kHz, 1.544 MHz, 2.048 MHz or 19.44 MHz.
  • Accepts two independent reference inputs which may have same or different nominal frequencies applied.
